Another pedestrian killed on Queens Blvd. This time a 58-year-old woman, hit, police believe, by a minivan that sped from the scene. This time at 71st Ave. Neighbors I interviewed for 1010 WINS say the city has tried to cut down on the pedestrian accidents by re-timing the lights and lowering the speed limit. But they say it's still a challenge crossing what they've dubbed the Boulevard of Death.
